@ bertiebassett: i know, but swisscom doesn't really support for a "normal customer" anyway - they want to charge a fortune each month.. and the software version on their site is 4.2.1.94.. so i decided to take the risk. it brought me internet and MMS which didn't work before so it was worth risking
i'll change to orange in a few weeks and get a "real working BB" by then.
